Question
![In a recent court case, it was found that during a period of 11 years, 893 people were selected for grand jury duty, and 42% of them were from the same ethnicity. Among those eligible for grand jury duty, 81% were of this ethnicity. Use a 0.05 significance level to test the claim that the selection process is biased against allowing this ethnicity to sit on the grand jury. Identify the null hypothesis, alternative hypothesis, test statistic, P-value, and provide a conclusion about the null hypothesis that addresses the original claim. Use the P-value method and the normal distribution as an approximation to the binomial distribution.
**Null Hypothesis (H₀):**
p = 0.81
**Alternative Hypothesis (H₁):**
p < 0.81
**What is the test statistic?**
z = -29.71
(Round to two decimal places as needed.)
**What is the P-value?**
P-value = ______
